Improvement in steam-radiators



UNITED STATES PATENT OFFICE- CHARLES W HITTIER, OF BOSTON, MASSACHUSETTS, ASSIGNOR TO HIMSELF AND BENJAMIN F. CAMPBELL, OF SAME PLACE.

IMPROVEMENT IN STEAM-RADIATORS.

Specification forming part of Letters Patent No. 8 1,037, dated November 10, 1868.

To all whom it may concern:

Be it known that 1, CHARLES WHITTIER, of the city of Boston, in the State of Massachusetts, have invented certain new and useful Improvement in Steam-Radiators; and do hereby declare the following to be a full, clear, and exact description thereof, reference being had to the accompanying drawings, and to the figures and letters marked thereon.

Of these drawings, Figure 1 is a plan view of a number of sections of a radiator. Fig. 2 is a longitudinal vertical section taken through the line 00 x of Fig. 1. Fig. 3 is a cross-vertical section taken through the line 1 y of same figure, and Fig. 4: is a cross-vertical section taken through the line 2 z of same figure.

Similar letters of reference indicate correspondi n g parts in the several figures.

My invention relates to improvements in that class of radiators generally used for indirect radiation, where the radiator consists of one or more series of sections, such sections being placed side by side or in a horizontal position, an en incased in any desired way. In forming these sections, in order to produce the greatest effect with the least amount of steam passed through them, I find it a great improvement to cast the openings in each section, so that the steam will pass from the one to the other in the same economical and rapid manner as it goes through the body of the section itself, thus preserving its duty of greater eii'ectiveness within a larger extent of radiating-surface than has been heretofore assigned such amount of steam. The steam, as it will be seen, passes through these sections in a very thin body, and drives all the fixed air be fore it. I therefore construct each section on opposite sides, near the ends, with an aperture of the same shape of the passage through the radiator for the narrow body of steam, as seen at a a, and these openings, when the sections are attached side by side, will come opposite each other and form a complete passage for such body of steam.

My improvements also permit of the sections being attached in horizontal layers by means that will not cause the joints or portions of the sections where they are connected, as above stated, to leak.

The series of horizontal sections of radiators have been heretofore connected together by means of rods or bolts, placed generally in the steam-passage when the position of the orifices across the whole series permitted of it, or else above or below, on the outside. The contraction and expansion of this long line of bolts have the eifect, in a short time, of cansing some of the joints to leak. To avoid all this, I connect the sections at alternate ends to each other, in the manner described, so that any one joint is not practically affected by the contraction or expansion of the fastening.

My means of fastening gives, also, the advantage of detaching or attaching any one of the sections without disturbing or unfastening the remaining ones. It consists in casting on the sections, at the ends thereof, lugs b b, above and below, with slots 0 c in them, open at the top. In these slots, where the steam-openings d d in the sections are opposite to each other, stout bolts 0 c are placed, which, when tightened by means of nuts at their ends, bring together the orifices mentioned, made steam-tight at their edges by proper packing.

I claim- 1. Constructing each section on opposite sides, near the ends, with an aperture, a, of same shape as aperture d of body of radiator, substantially as and for the purposes described.

2. Connecting the alternate ends of the radiator by means of lugs I) I) I) b, &c., and bolts 0, &c., constructed substantially as described.

CHARLES WHITTIER.
